modernize-use-override¶

Adds override (introduced in C++11) to overridden virtual functions and removes virtual from those functions as it is not required.

virtual on non base class implementations was used to help indiciate to the user that a function was virtual. C++ compilers did not use the presence of this to signify an overriden function.

In C++ 11 override and final keywords were introduced to allow overridden functions to be marked appropriately. Their presence allows compilers to verify that an overridden function correctly overrides a base class implementation.

This can be useful as compilers can generate a compile time error when:

• The base class implementation function signature changes.
• The user has not created the override with the correct signature.

Options¶

IgnoreDestructors

If set to non-zero, this check will not diagnose destructors. Default is 0.

OverrideSpelling

Specifies a macro to use instead of override. This is useful when maintaining source code that also needs to compile with a pre-C++11 compiler.

FinalSpelling

Specifies a macro to use instead of final. This is useful when maintaining source code that also needs to compile with a pre-C++11 compiler.
